Wow watta steal………… 
There’s one born every minute…
Note the changes to my signature. The OT 50L is the Reference Standard for determining TCR. If a particular flash demonstrates any TCR flaw then the highest rating it can reach is 9.5. For every TCR flaw the rating is adjusted downward by .5 in the 1-10 scale.
The Dollar Tree light I reviewed four years ago, with a whopping 8 lumens out the front.

i doubt the ot50l is much of a reference standard for anything.
as i noted earlier the color rendering is beat by the ebay 5mm leds.
and i doubt those are the best.
Thanks for shorten it. Much appreciated.
Has been given… 
Have you and snakebit bought one?
No, right?
Butt ya come on here like ya know from firsthand experience. :person_facepalming:
PS. I removed “has been given” and replaced it with “has a”.
Thx for pointing that out. Semantics can be important to some that like ta nitpick so that they can appear superior. 
PSS. Snakebit apparently has bought one so I stand corrected. He sez that some 9 led ebay high CRI flash beats it like a red-head stepchild. I’d have to know exactly which e-bay 9 led this is, buy one, and then compare the two.
How about removing all doubt by investing a $1.00? :laughing: Then talk.
You claim it’s beat by ebay 5mm leds. Exactly watt leds I haven’t a clue. Not that it’s relevant. So again, how do you know if you haven’t bought one to compare?
PS. If ya need a $1.00 lemme know and I’ll paypal it over. :money_mouth_face:
PSS. Oops. Looks like it sold-out online already. Better invest that $1.00 and get that TCR Reference Standard in person. Ya don’t wanna look like yer talking outta yer, ya know watt, like a couple here. :laughing:

Is that what they call jumping to conclusions?
Come on, you know some of my postings. No chance I could trick anyone into thinking that.
Well, are you gonna walk the talk or not?

Read earlier in the thread and you will remember that snake already tested this light.
I don’t own this light, and never said I do.
How about you starting with a range of LEDs you own and tell us the corresponding TCR values? Might be interesting to correlate nawj-TCRs with CRI.
Ok. That’s his opinion. I think he’s wrong. Unless he got an anomaly then he’s right. :laughing:
PS. Do ya mean this “test”? Doesn’t look like much of a test to me. :laughing:
Ya know it’s coincidentally funny ya mention this. I have a LOT of flashes. Plenty of them old-school. One of those old-schools is a completely stock Trustfire X8 with an XML-T6.
By today’s standards a supposed joke, right? Almost ancient. :laughing:
Well as I woke up this early dark morning due to one of my property sensor alarms going off. I grab the X8 and start walking the 5 acres. I keep flashes handy all over the place so first come first served.
Geez. As I’m lighting things up everywhere I noticed how perfect the TCR on this thing is. Every color and its variation is a 10. Amazing? IDK. It just is. Just like the OT 50L.
Go figure. 
PS. Ok ya don’t own the light. Right there ya gotta stop. Why are you involved here? Don’t twist things back to me. Ya talk like yer giving an accurate assessment of its TCR performance. How is that logically possible?
SB did a buy and test in 2020, if it was this one, then it isn’t the same as the 2021 version. This one doesn’t look the same: the marking on the tube uses a big dot or dash and the “L” is written with a hollow letter versus a solid letter in the ’21 version. The new ones don’t have the orange washer. This one also appears to have several 5mm emitters versus a single round emitter in the ’21. And the ’21 tail cap design is different, less taper and longer grooves.

I did test the color rendering on the ot50l compared to several common leds.
That it is beat by the ebay leds should give you an idea.
I didnt even have to haul out a 219b sw45 to compare.
The ebay leds are used in photographic light panels.
The ot50l is designed to be cheap.
Huge sample to sample variations are the norm with cheap stuff.
Like i said its usable.
Where? I said nothing about this light, at least, I didn’t meant to. Sorry if any of my postings were confusing.
What is it good for in this context in the first place? You already named sunlight as your reference. Now you exclude users from this discussion if they don’t own this budget light. Is that reasonable? Thus far, I seem to be the only one taking you half-serious, so be kind please .
About your experience with the XM-L: I agree that LEDs from the post angry-blue era are very convincing. I even like to take something like a CW XHP70 light with me, and it’s fully sufficient to tell blue from green from red.
But I do. And if you refuse to invest some time to investigate your own idea, why should anyone else? Do yourself a favour and let your TCR standard shine onto your hands. Then do the same under sunlight. I have never seen this this light, but I bet you’ll have to subtract some points.
@kennybobby, sorry for OT. If it’s not ok, I’ll delete my postings.
@Unheard, No problem, it’s all good. Free, Fair and Open discussions help get to the best answers and solutions.
i like to challenge and test my assumptions and beliefs about things that i think i know to make sure that i’m not fooling myself.
s. i did your sunlight test on the back of my hands. The colors look to be the same to me, but it’s hard to beat the intensity of old Sol with a 50 Lemon beater. So i tried it in the shade and in indirect sunlight from ambient reflections and scattering, so the intensity was less. Same trueness to the coloring. Direct sun is almost too intense and overwhelms the eyeballs.
Kinda some blanket statements here. You don’t know if the OT 50L has a lot of sample variations just becuz it’s cheap. You assume it’s a blanket-wide norm through experience with other cheap lights. Can’t argue with watt ya know. Ya know watt ya know and that’s that. However this isn’t another run of the mill cheap light. Butt you do say it’s ‘usable’ so we have that.
It doesn’t give me a real world idea becuz that’s not watt my eyes and others tell. It is watt it is. The OT 50L is plenty good enuff for purposes of subjective TCR. Subjective TCR is better supported only through consensus. That’s the only way subjective analysis of anything gets reasonably deserved credence. It may not be scientifically measured as perfect but neither are your references. Nothing is. For a purely hypothetical example, IF it averages over a broad sampling at 99.2% CRI device measured accurate and IF your references are 99.7% accurate this still isn’t enuff of a difference to discount it as a standard. The average human eye will not discern these differences just like measuring lumens by sight only. A calibrated measuring device will. Again those minute differences in reality has little to do with TCR reality.
I hope we don’t expect too much doing these comparisons. As the saying goes, “Expectation is the mother of all frustration.” We don’t need to get frustrated here.
Anyway, Sb, you, and Kennyrobby deserve a BIG kudos for finding it (and its earlier variations) and following through with it here for the new and improved 2021 version. I certainly appreciate it. I think many others will too. You all started it.
At $1.00, it’s a bargain. As a TCR Standard Reference, a widely available SUPER bargain. And I hope lot’s of folks invest $1.00 to see exactly watt I’m talking about.
